Morse code card: common questions
What microcontroller does the Morse code card use?
The Morse code card is built around the CH32V203GXUX, from the RISC-V family.
How big is the Morse code card PCB?
The Morse code card measures 85.6 × 54 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Morse code card?
44 components, from 8 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Morse code card design files?
From the maker-lukas/morse-code-card repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Morse code card design in my own project?
The repository has no license, so all rights stay with maker-lukas. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Morse code card without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
